<p>The twist stop roller has several radially protruding guide teeth (4.1,4.2) that are provided at outer periphery of a symmetric ceramic structure (1) for formation of zigzag thread track (20). The ceramic structure is rotationally fixed to a locking bush (10). The inner bearing sleeve (13) and outer clamping sleeve (11) are formed in the locking bush. The inner bearing sleeve and outer clamping sleeve are radially connected to each other through radial holding bars (12). The deformable clamping tabs (15) are distributed at clamping surface (16) of ceramic structure.</p> |
